Common use of Spray Cooling, Forced Vaporisation and use of Boil-Off Clause in Contracts

Spray Cooling, Forced Vaporisation and use of Boil-Off. (a) If on any sea passage, Charterers order the Vessel to force vaporise LNG to eliminate or minimise the use of bunkers and the order is complied with, the Boil-Off guarantee shall be deemed to have been complied with on that sea passage. (b) The master shall notify Charterers if he/she is of the opinion that the Vessel will not, on arrival at the loading port, be able to commence bulk loading within half an hour after cooling of the loading arms without spray cooling on the ballast sea passage. (c) Without prejudice to any of Owners’ or Charterers’ obligations under this Article 9; if Owners intend to order spray cooling at any time during the charter period, Owners agree, if requested by Charterers, to discuss the reasons and technical basis for spray cooling. (d) Subject to the provisions of this Charter, Owners shall have free use of Boil-Off. Owners shall exercise due diligence to minimise the use of the GCU during the normal operation of the vessel. At no time during the charter period, (except for safety reasons) shall the Vessel use the vent system as a primary means of controlling the cargo tank pressures. Any such safety related venting, or venting caused by any other reason, shall immediately be reported to Charterers (as required in Appendix B) with full explanation as to why venting was required and duration and quantity of venting. (e) Each of the Vessel’s four diesel generators is to be equipped with a dual system to burn either Boil-Off gas from the LNG carried (together with a diesel pilot oil) or, diesel oil alone or heavy fuel oil (together with a diesel pilot oil) as independent of the other engines as the Vessel’s design allows. The Vessel shall, at Charterers’ option, use the available Boil-Off gas, or fuel, or complement the boil-off gas being used as fuel by forced vaporised natural gas or by fuel oil, within such limits as may be imposed by Charterers and, in any event, by safety regulations and the safety of the Vessel.

Spray Cooling, Forced Vaporisation and use of Boil-Off. (a) If on Contractor requires or if Charterer so requests, the Vessel shall spray cool as necessary in a manner consistent with Contractor’s or Charterer’s requirements so as to maximise the use of the available Boil-Off for propulsion, whilst using due diligence to avoid the generation of any excess Boil-Off. (b) If during any sea passage, Charterers order passage Charterer orders the Vessel to force vaporise LNG to eliminate or minimise the use of bunkers and the order is complied with, the Boil-Off guarantee relevant to such operation shall be deemed to have been complied with on that sea passagefor the tank from which the LNG has been pumped. (bc) The master Parties agree that the Master shall notify Charterers Charterer if he/she he is of the opinion that the Vessel will not, on arrival at the any LNG loading port, be able to commence bulk loading within half an hour ***** after cooling of the loading arms without spray cooling on the ballast sea passage. (cd) Without prejudice to any of Owners’ Owner’s or Charterers’ Charterer’s obligations under this Article 9; , if Owners intend Owner or Contractor intends to order spray cooling at any time during the charter periodCharter Period, Owners agreeOwner agrees, if requested by CharterersCharterer, to discuss provide written notice of the reasons and technical basis for spray cooling. (de) Subject to the provisions of this Charter, Owners Owner shall have free use of Boil-Off. Owners Except when otherwise required pursuant to Charterer’s orders, Owner shall exercise due diligence to minimise the use any venting or steam dumping of the GCU during the normal operation of the vessel. At no time during the charter period, (except for safety reasons) shall the Vessel use the vent system as a primary means of controlling the cargo tank pressures. Any such safety related venting, or venting caused by any other reason, shall immediately be reported to Charterers (as required in Appendix B) with full explanation as to why venting was required and duration and quantity of venting. (e) Each of the Vessel’s four diesel generators is to be equipped with a dual system to burn either Boil-Off gas from the LNG carried (together with a diesel pilot oil) or, diesel oil alone or heavy during periods of low fuel oil (together with a diesel pilot oil) as independent of the other engines as the Vessel’s design allows. The Vessel shall, at Charterers’ option, use the available Boil-Off gas, or fuel, or complement the boil-off gas being used as fuel by forced vaporised natural gas or by fuel oil, within such limits as may be imposed by Charterers and, in any event, by safety regulations and the safety of the Vesseldemand.

Spray Cooling, Forced Vaporisation and use of Boil-Off. (a) If Owner requires or Charterer so requests, the Vessel shall spray cool as necessary in a manner consistent with Owner’s or Charterer’s requirements so as to maximise the use of the available Boil-Off for propulsion, whilst using due diligence to avoid the generation of any excess Boil-Off. (b) If on any sea passage, Charterers order passage Charterer orders the Vessel to force vaporise LNG to eliminate or minimise the use of bunkers and the order is complied with, the Boil-Off guarantee shall be deemed to have been complied with on that sea passage. (bc) The master Master shall notify Charterers Charterer if he/she he is of the opinion that the Vessel will not, on arrival at the loading port, be able to commence bulk loading within half an hour thirty (30) minutes after cooling of the loading arms without spray cooling on the ballast sea passage. (cd) Without prejudice to any of Owners’ Owner’s or Charterers’ Charterer’s obligations under this Article 9; , if Owners intend Owner intends to order spray cooling at any time during the charter period, Owners agreeCharter Period Owner agrees, if requested by CharterersCharterer, to discuss the reasons and technical basis for spray cooling. (de) Subject to the provisions of this CharterTime Charter Party, Owners Owner shall have free use of Boil-Off. Owners Except when otherwise required pursuant to Charterer’s orders, Owner shall exercise due diligence to minimise the use any venting or steam dumping of the GCU Boil-Off during the normal operation periods of the vessel. At no time during the charter period, (except for safety reasons) shall the Vessel use the vent system as a primary means of controlling the cargo tank pressures.
